I think 1~1.15 bitcoin is right price. If its over 1.5, I'm out

0.85 BTC or less. just look at the diff numbers

For me I can make .9 btc work even 1.0 btc  but higher then 1.0 btc

I may just look into the rk-box miners or the tube miners from AM

Today, you can buy the last AntMiner S2 1TH/s Miner Batch 4  at the cost of 1450 USD (https://bitmaintech.com/productDetail.htm?pid=00020140429083756017VwGm90Xx06B5)


I'd rather not buy over priced S3.
S2=1450.-   
Take off 2 fans, displey, power supply and more expensive shipping cost and divide by two and get the S3 price.

less than 1 BTC. They are still making HUGE profit.

It will be great if it's under 1

Assuming they ship in early July .75 BTC would be reasonable.  Anything more than that would be a really tough sell at the current BTC price.

I think it's a mistake to invest in any Bitcoin mining hardware until the difficulty settles down a bit.

KNC appears to be killing the difficulty right now with the Neptune, and it's hard to say where it will finally level out. Bitmain's timing with the S3 could not have been worse for them from a pricing standpoint.

I had planned on buying quite a few batch one S3s, but after seeing the difficulty get murdered like it is right now, I'm not going to buy any unless they are offered at rock bottom prices (under $1/GH).

Here is food for thought:

Also, the network daily growth rate appears to have either leveled out or is heading back up:

Proceed with caution. I'm glad I don't have any hardware pre-orders that won't be delivered until August or September!

How? this doesn't make a lot of sense to me.

Assuming 1% hashrate growth per day (which is lower than we've seen anytime in recent memory (http://bitcoin.sipa.be/growth.png)), .15/kwh power @$593/btc, and delivery on July 15th, the income should peak out at 0.92 BTC in a couple months.   1.0 BTC sounds like a nearly guaranteed loss— it's a strong bet that hashpower will suddenly stop growing, unless you're not paying for power.

I loved the Bitmain S1 (S2 appeared less often, I'm glad to see the S3 looking more like the S1 design) but break even before considering the costs of power/cooling/psu or trouble is not a good deal, not for the miner or the ecosystem. I hope Bitmain will be willing and able to get a bit more aggressive with the prices.

There is considerable risk in mining— including the risk that the Bitcoin community chooses to make some miner breaking POW changes to improve some of the centralization problems. I'm not saying people should be guaranteed a windfall, but if people are taking on risks without a solid prospect of being compensated for them I think they're crazy.

if they start shipping next month, i prefer around 0.8-0.9 BTC
maybe if difficulty stop raise like crazy, i'll consider to buy 3 of them ;D

EDIT : hmm i see some group buys said the price will be around 1.1-1.25 BTC  :-\

He probably has dirty cheap electricity like I do, $0.04/kwh

I have a feeling that Bitmain is going to wait for S2 to be sold out first, before S3 becomes available

i don't think so
since S2 and S3 have different price range
they can sell S2 and S3 together :P

if that is the case then what is the hold up? 3 days have been passed ::)

About $250, cause I'm pretty sure I could resell it for more.

If we lived in a fantasy land where I couldn't resell the hardware, I'd pay about $100 for it.

They announced yesterday that they were delaying announcing the price by a week.

We can all wait for a few weeks they will mine on their onw and then sold it to us...
If price is about 1 btc for 500 ghs am in otherwise I can buy the rockminer

I didn't know that. The price should be below 1 then

Delaying the release a week affects your price that much? Obviously the price should be below 1 BTC. I cannot stand when ignorant people say they would be willing to pay over 1 BTC. You will never make any money in that case.

Price needs to be around 0.7 BTC for me to even consider buying any units.

Yes, it does. If you include the process and shipping time then you are looking at least one week delay. By this time the difficulty probably will rise another 10~20%. We are in hashing race now

Well earnings decrease similar to exponential decay.  More than 1/2 your earning come from the first month of mining.  If the S3 arrived 1 difficulty period late you're basically down 30% in earnings.

7 days is a hashrate change of 1.072x under 1%/day assumption— which suggests that you should pay 0.9327x the price you were willing to pay before—, recent growth (http://bitcoin.sipa.be/growth-10k.png) looks more like 2%/day which would be 1.148x the hashrate in 7 days— which suggests you should pay 0.87x the price. Obviously S3 itself shipping in quantity will also drive rates higher…

Obviously the exact timing of the target matters when you're getting down to details like this, but in general small timing difference can make a big difference in income.  It may not matter that much unless you're already right at the verge of a sure loss, but the trend with mining hardware lately has been to sell at near or across that boundary.

I understand this. I was just trying to point out that the price he was originally willing to pay was too high
